JACK JUMPER ANT FACTS

IdentificationThe Jack Jumper Ant is a large species of Bulldog Ant. They have a jumping motion when disturbed which gives them their common name. The workers are black with yellow mandibles, antennae, and lower parts of the legs. The head is slightly broader than it is long and mandibles are slightly shorter than the head. The mandibles have four large sharp teeth with a smaller tooth in between each large one. The queen is similar in colour to the workers but is larger and more robust.
